machine which blows the poisoned dust over the rows of cotton. The boll-weevils are killed by inhaling the insecticide, and the effectiveness of the mixture does not depend upon their sucking it, as is the case with various prior insecticides used for killing bollweevils. Thorough tests of the compound have shown that the boll-weevils are killed within between one and twelve hours after the application of my compound.

What I claim is An insecticide compound for killing boll weevils as a result of their inhalation of the compound, consisting of a solution of arsenic and baking soda in water said solution being boiled until the ingredients are dissolved in the water, in combination with a large quantity of wood ashes with which the poisoned solution is thoroughly mingled and then dried in accordance with the steps hereinbefore specified and for the purposes described.

PHILIPP KOENIG.
